Abstract: A cell phone device having a camera, an imaging unit and a display unit, which are joined with each other. The imaging unit and the display unit may be separated and used in a separated state. A display housing includes the display unit, a speaker, and a microphone. A keypad housing includes the imaging unit. The display housing and the keypad housing each include a local communication IF unit for performing wireless communication and a battery for supplying power to each function block. When the display housing and the keypad housing are separated, the image generated by the imaging unit is output to the display unit via the local communication IF units. A recording instruction is then generated by operating the display housing while checking the image on the display unit.

Abstract: An electronic control device transmits a function control signal within a predetermined area. Other electronic devices within the predetermined area receive the function control signal. The function control signal initiates a control program in an electronic device in the predetermined area that adjusts one or more user setting conditions of the electronic device, such as audio volume level, display brightness level, etc. The original user setting conditions are returned to their prior values when the device exits the predetermined area or otherwise stops receiving the function control signal.
